At ComEd, we provide electronic tariff documents (in pdf format) for the convenience of our residential and business customers. Our tariffs are subject to regulatory review and approval by the Illinois Commerce Commission (ICC). However, users of electronic tariffs should note these tariffs are not the official documents and users assume responsibility for reliance upon tariffs in electronic format.
Although ComEd aims to have this information current at all times, it should be emphasized that the rates and provisions in the tariffs are subject to revision. All of the tariffs below have been approved by the ICC. Notification of proposed changes to ComEd's tariffs are not provided on this website.
